Ok once more: the form page looks like this (stripped for testing purpose). I can upload an (jpg) image with a max size of 250kb and everything works fine. Bigger than that the form page is NOT sent, and the update page never reached.
<title>Website Maintenance</title>
<link href="../css/admin.css" rel="stylesheet" type="text/css" />
<script language="JavaScript"><!--function for progress icon-->
function setVisibility(id, visibility) {
document.getElementById(id).style.display = visibility;
}
</script>
</head>
<body>
<form action="update.php" method="post" enctype="multipart/form-data">
<h2>New Picture</h2>
<table width="auto" align="center" border="1" bordercolor="#900" cellspacing="0" cellpadding="3">
<tr height="30">
<td style="color:#FFF" width="100">New Picture </td>
<td align="center">
<input type="file" name="Foto" />
</td>
<td style="color:#FFF" width="195" id="formupdate_italic">Max upload size = 6 Mb (6000kb)</td>
</tr>
</table><br /><br />
<table width="auto" align="center" border="1" bordercolor="#333" cellspacing="0" cellpadding="3" bgcolor="#00CC00">
<tr height="30" align="center"><td width="20">
<input type="submit" onclick="setVisibility('progress_icon', 'inline');" name="edit" value="save"/></td></tr>
</table>
<!--div for showing upload in progress-->
<div class="progress_icon" id="progress_icon" align="center">
<table width="100%" border="0">
<tr>
<td align="center"><br />Uploading Image to your Database, please wait....</td>
</tr>
<tr>
<td align="center" style="font-size:11px">
<br />Average upload time for : 1MB -> 30 sec. , 2MB -> 45 sec. , 4MB -> 90 sec. , 6MB -> 3 min.<br />
<br />For faster uploads resize your images to 2100pixels x 1400pixels x 72dpi !! ( jpeg quality 10 )<br />
<br />Images are resized before uploading, so you only loose time trying to upload bigger images.
<br />Horizontal panoramic images should have a max. height of 1400px for fast uploading.
</td>
</tr>
</table>
<br />
</div>
</form>
</body>
</html>
And this is the page (update.php)for processing which i stripped to be sure that nothing is wrong there, but it is never reached by the form submission.
<?php
$Foto = $_FILES['Foto']['name'];
echo 'you have reached the upload page succesfully.<br />
you normally would have uploaded '. $Foto. ' to our datebase,<br />
but in this case it is just a testing page';
?>
